Your cabana is made of the best quality, long lasting materials. It will last for decades without any finishing, but all wood will weather to a silver driftwood gray over time. If you want to maintain the new look, you should protect it with a quality sealer. This will also protect it from drying out, checking (small hairline splits on the surface of the wood), as well as from damage caused from UV rays. Select this option if you would like us to apply two coats of a high quality sealer with a slight cedar tint before we ship your cabana.
